What were the long term effects of Krakatoa?

What were the long term effects of Krakatoa?

The eruption also produced erratic weather and spectacular sunsets throughout the world for many months afterwards, as a result of sunlight reflected from suspended dust particles ejected by the volcano high into Earth’s atmosphere.

What were the effects of the Krakatoa eruption in 1883?

It is estimated that more than 36,000 people died. Many died as a result of thermal injury from the blasts and many more were victims of the tsunamis that followed the collapse of the volcano into the caldera below sea level. The eruption also affected the climate and caused temperatures to drop all over the world.

What are the long term effects of a volcanic eruption?

Impacts on Human Health Health effects inlcude respiratory problems, eye problems, and skin irritiation. One long-term effect of volcanic ash is silicosis. Silicosis is a disease resulting in lung impairment and scarring, from exposure to particles of free crystalline silica.

What was the aftermath of the Krakatoa eruption?

Approximately 1,000 people were killed in Sumatra; there were no survivors from the 3,000 people on the island of Sebesi.

How has Krakatoa changed over time?

In late 1927, Krakatoa reawakened, producing steam and debris. In early 1928, the rim of a new cone appeared above sea level, and it grew into a small island within a year. Called Anak Krakatoa (“child of Krakatoa”), the island has continued to grow to an elevation of some 1,000 feet, and erupts mildly at times.

What caused Krakatoa to erupt?

The Krakatoa eruptions were caused by the subduction of the Indo-Australian tectonic plate as it moved northward towards mainland Asia. Subduction is a geological process by which one edge of a crustal plate is forced sideways and downward into the mantle below another plate.

What impact did Krakatoa have on the world?

Krakatoa eruption cooled the world. WHEN the Indonesian volcano Krakatoa erupted in 1883, sending 25 cubic kilometres of rock and ash into the air, it did more than generate the loudest sound ever recorded. It also cooled the world’s oceans and suppressed rises in sea level for decades afterwards.

How often does Krakatoa erupt?

The island is called Anak Krakatau, which means child-of-Krakatau. It is pretty much erupting all the time at a low level, but once or twice a year it has slightly larger eruptions that people notice and sometimes report in the news.
